What does the raw value for the get_bloginfo’s filter argument exactly do?

by

The $filter argument for the get_bloginfo function has a default value of raw but WordPress’ Code Reference didn’t mention another allowed values. What this raw stands for and what are other possible values if any?

We have the following filters added by default (source)

add_filter( 'bloginfo', 'wptexturize'   );
add_filter( 'bloginfo', 'convert_chars' );
add_filter( 'bloginfo', 'esc_html'      );

The bloginfo filter (source) is applied on the get_bloginfo() output, in the display mode, except for the url that has it’s own bloginfo_url filter. The core isn’t using that url filter currently and there’s a wontfix (see #26803) on escaping the url in display mode.

So the raw mode, skips these filters.

The bloginfo() function is a wrapper for get_bloginfo() in display mode (source).
